Abstract

A height control valve (50) is preferably adapted to be mounted in a trailin g arm suspension and fluidly interconnected to a source (58) of pressurized ai r and to an air spring (52). The height control valve (50) comprises a housing (61) having a cylindrical bore (76), a supply port (62), an exhaust port (70 ) and an air spring port (66) each of which extends through the housing (61) a nd fluidly communicates with the bore (76). A rotor (78) is preferably rotatabl y mounted in the bore (76) and interconnected to the arm wherein pivotal movement of the arm rotates the rotor (78) with respect to the housing (61) between first, second and third rotational positions. A plurality of seals (88, 90, 92, 94) is preferably located between the rotor (78) and the bore (76) defining a flow passage between the bore (76) and the rotor (78) wherei n in the first rotational position, the flow passage isolates the air spring port (66) from both the supply port (62) and the exhaust port (70), in the second rotational position the flow passage interconnects the air spring por t (66) with the supply port (62), and in the third rotational position the flo w passage interconnects the air spring port (66) with the exhaust port (70).</ SDOAB>
